Rodo Koletti, the father-in-law of accused conwoman Melissa Caddick, has broken his silence on her disappearance in a bombshell 60 Minutes interview.

Koletti said his son, Anthony Koletti, is in “delusion and denial” over claims that his daughter-in-law knocked off more than $25 million from investors.

“He doesn’t want to believe that the woman he loves and married is capable of it, but unfortunately the proof’s stacking up so much against her,” Rodo Koletti said in the interview.

“He believes she was set up and he was going to look at suing ASIC and everybody else for raiding their house.

“It’s a hard time for everybody and it will take a very, very long time for everybody to get over it,” he said.

Rodo Koletti revealed that he also wound up a victim of Melissa Caddick as she had forged his signature to verify her fraudulent documents.

Koletti claims that he was unaware that his signature had been forged until he was interviewed by 60 Minutes.

“If you see my signature, it’s very distinctive and that is not it,” he said.

“It’s a hard time for everybody and it will take a very, very long time for everybody to get over it.”

Koletti believes his son was not involved in the scheme whipped up by Melissa Caddick and wants it to be known that he is innocent.

“Anthony is a hairdresser. I don’t believe he has the capacity to know what a financial scheme is. I don’t think he could have been in it at all or known what was going on,” he said.

This is the first time any of Caddick’s family have spoken out since she went missing and was ultimately pronounced dead after a shoe containing her DNA was discovered.

The announcement comes after it was revealed that Melissa Caddick had just $5,600 in her bank account when she went missing three months ago.
